# Opt-Out Keywords for SMS Messages in Marketing Cloud Next

To meet consent and privacy regulations, your recipients must know how to opt-out of SMS messages. In your messages, provide specific opt-out keywords and clear instructions for using them. Include keywords in promotional or transactional messages every time you send.

[View supported editions](https://help.salesforce.com/s/articleView?id=mktg.mktg_editions.htm&release=264.0.0&type=5 "Marketing Cloud Next is available in Growth and Advanced editions, and requires Salesforce Enterprise or Unlimited editions. Some features are limited by edition or purchased add-on. All functionality is available in Lightning Experience only.").

Every SMS sender code reserves keywords that recipients use to opt out of receiving messages. These keywords are always reserved.

- STOP
- QUIT
- CANCEL
- END
- UNSUBSCRIBE

Note Only short and long codes support opt-out keywords. Alphanumeric sender IDs don’t support two-way messaging, so recipients can’t reply to opt out.

A marketing admin can assign custom opt-out keywords to sender codes in Salesforce Setup. In the body of your SMS message, include one of these keywords and brief opt-out instructions.

To opt out, a recipient must reply to the sender code with an opt-out keyword appearing before the first space in their message. Salesforce immediately unsubscribes the recipient from all messages from that sender code.

![Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mktg_all-264-0-0-production-enus/e92be4e1-4bef-47a5-a11d-95f4ea1f7d7a/images/icon_example.png)

Example

Try one of these SMS opt-out instructions that are fewer than 25 characters:

- Text STOP to opt out.
- Reply QUIT to end.
